Question

In order to correct the power factor of a motor, 0.00045 farads of capacitance must be connected in parallel with the motor. Express this in microfarads.

a. 450
b. 4500
c. 45
d. 0.000045

Answer 1

0.00045 farads is equal to 450 microfarads after converting farads to microfarads by multiplying by 1,000,000. Therefore option a is the correct answer.

Step-by-step explanation:

To express the capacitance in microfarads, you simply need to convert farads to microfarads by multiplying by the factor of 1,000,000 (since 1 farad = 1,000,000 microfarads).

Therefore, 0.00045 farads multiplied by 1,000,000 equals 450 microfarads.

The correct answer would be option a) 450.
